Thats a neat project, and you should feel proud of it! Especially for a first project!

Durring a pause statement, the micro just sits there counting time. It can do no math, or anything. What happens if you set this to something like 14 ms? The idea is that the epprom write takes another 5 ms, and we'll give the math 1 ms.

It would be a little faster doing it with 8 mhz, so you might as well set it there. I have to get back to work, but I will comment some more tonight.
